Knee pain can be a real bone of contention for many folks. Excuse the pun... :)
As we age the supporting ligaments of our joints become laxer. This can lead to joint instability problems and discomfort eventually leading to pain and loss of mobility.
The feet namely the arch of the foot is a key component in supporting the knee joint. However, arches do drop due to ligament laxity, aging or genetics.
Exercises can help the foot and knee ligaments. Research also supports the use of custom orthotics to assist the feet and allow better alignment of the knee. Hence, preventing further degenerative joint issues in the long run.
